Core Purpose and Depth
Math SL provides a comprehensive foundation in algebra, functions, trigonometry, introductory calculus, vectors, and statistics. It is designed to build mathematical literacy and confidence without excessive abstraction.
Math HL extends far beyond this foundation. It includes advanced calculus, proof techniques, complex numbers, series, differential equations, and highly rigorous problem-solving. HL requires abstract thinking, logical structure, and the ability to sustain multi-step reasoning across unfamiliar problems. This significantly increases both conceptual depth and cognitive demand.
RevisionDojo’s curriculum comparisons consistently highlight how HL mathematics moves from application to theory-driven analysis.
Instructional Hours and Content Load
Math SL requires approximately 150 teaching hours.
Math HL requires around 240 teaching hours, covering all SL material plus extensive HL-only topics such as mathematical induction, advanced calculus, and differential equations.
Student feedback and curriculum breakdowns consistently note that HL adds roughly a dozen additional subtopics, increasing both pace and workload.
Exam Structure Differences
Math SL assessment consists of:
- Paper 1 (non-calculator, 90 minutes)
- Paper 2 (calculator, 90 minutes)
- Internal Assessment (20%)
Math HL assessment includes:
- Paper 1 (120 minutes)
- Paper 2 (120 minutes)
- Paper 3 (calculator, 60 minutes, HL-only)
- Internal Assessment (20%)
The additional Paper 3 in HL focuses on unfamiliar problem-solving and mathematical reasoning under pressure.
Internal Assessment Expectations
Both SL and HL students complete a Mathematical Exploration of approximately 6–12 pages.
